Salzer UK has a reliable range of Mains Changeover Switches and Bypass switches from 20Amps to 315Amps, with 1, 2, 3 or 4 pole options available.
Mains changeover switches are manually operated changeover switches with overlapping contacts (make before break), which allow a 1-pole, 2-pole (1-pole + N), 3-pole and 4-pole (3-pole + N) changeover. They enable electrical supply or load changeover for maintenance purposes.
With bypass switches, the energy flow can be changed from the UPS supply to the direct mains supply without interruption and with the UPS input either connected or disconnected. Bypass switches can be configured as 1-pole, 2-pole (1-pole + N), 3-pole and 4-pole (3-pole + N) versions.
